I've got my SKS fenders mounted and that big silver thing on the right is my new TrailTech HID light, from Batteryspace.com .. Holy crap it is bright. I did a nice loop down Blossom Hill and back over the hill on Shannon Road, and the light really did great on the dark backroads, even descending at 30 mph. I never felt like I was "outrunning" it, my only concern was aiming it down when cars came up the other direction towards me so I wasn't blinding the drivers. I may write and see if I can try the 6-degree spot reflector rather than the 12-deg flood that I chose, but again this is a question of courtesy rather than the 12-degree being insufficient. Quite a nice product and a great deal at $200. (For a comparison, this is the same bulb, housing, ballast and reflector as the Topeak Moonshine HID which regularly goes for $399 and is on sale this week at Performance for $300!)
